For Stefan, there is no mountain too high or Excel file too big…

Champion of ‘deep data’ at Peak, Stefan got his start in corporate finance at First Dutch advisory and went on to lead entrepreneur-backed Javest Investment Fund. By the time he joined Peak in 2015, Stefan had spent years supporting teams from seed to growth stage and navigating a jungle of fundraising, mergers & acquisitions, financing structures, company valuations, and management buy-outs at an international scale.

Don’t let the financial background fool you, Stefan is our resident philosopher, psychologist, and, thanks to his infamous whiteboard diagrams, our resident artist, too. At Peak, Stefan fights for our founders at every stage, armed with meticulous attention to detail and quick wit.

“Built it, scaled it, funded it”

As co-founder and former CEO of Studocu, he scaled a student marketplace from a university side project into a global platform serving tens of millions of users monthly. That journey from MVP to hypergrowth to institutional backing to international expansion, is why he’s valuable at Peak. He knows what hypergrowth actually feels like, not from theory.

Marnix brings an operator’s mindset to everything. He’s analytical but hands-on, competitive by nature, and impatient with slow thinking. At Peak, he focuses on early-stage companies that need a founder who understands what it actually takes to win.

When he’s not thinking about the next great European company ;), you’ll find him playing board games, play tennis, exploring the mountains or enjoy good food and wine with friends.

Numbers, neurons, and novel ideas…

Equal parts data wonk, product sleuth, and psychology aficionada, Tea has been an AI evangelist since before it was trendy and loves to pair deep data analysis with a curiosity for human behavior, decoding why products resonate and teams succeed.

She honed her craft in tech M&A, guiding global giants through high-stakes deals, before swapping spreadsheets for seed rounds to back the next generation of visionaries.

Her VC path kicked off at Newion, where she backed rising B2B SaaS stars such as Parloa, Salonkee and Dexter, helping guide them through their early scaling sprints. Fueled by her lifelong passion for education, she later took an entrepreneurial leap, helping build Mediahuis’s venture arm and shape its thesis in EdTech & the Future of Work.

Drawn to Peak’s entrepreneurial DNA and day-zero mindset, where scrappy hustle meets rigorous thinking, Tea now roams the Benelux hunting software founders ready to turn audacious ideas into category-defining companies.

Speaking seven languages and having called five countries home, she’s a globally minded geek who’s always game for a sci-fi debate, world exploration, or a culinary experiment.

From slinging stacks to head of Benelux.

Like a true dutchman, Thijs grew up hustling in a pancake restaurant. A long journey from slinging stacks, Thijs now leads all of our Benelux sourcing. He comes from the finance world. Before joining us in 2017, he learned a thing-or-two about global data services at Willis Towers Watson and started investing at The Mutual Fund, a collaborative portfolio managed by investors.

In Peak’s family of big characters, Thijs has both feet on the ground: he is the voice of reason and the bridge between gut instinct and deep data.

#1 fan of pen and paper

David’s been around the block. He started his entrepreneurial adventure as a Managing Director at Rocket Internet, a boots-on-the-ground rollercoaster of building up companies from Singapore to Bangladesh, or as he recalls it, “(obviously) the craziest time of my life.”

Afterward, he co-founded painting marketplace Weissmaler together with a former Rocket colleague. His founder days taught him lessons that he keeps with him to this day; “We scaled fast, serving hundreds of clients within months. We raised three seed rounds and hired 30 people within a year. Perhaps we went too fast: the business did not make it in the end.”

At Peak, David brings a hard-analytic skillset and pragmatic day-to-day experience. Part of the sharp-data team, David geeks out over growth metrics, number crunching, and bikes.
